GAS-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 485,910, `datedNovember 8, 1892. Application led April 80, 1892. Serial No. l131,354.(No model.)

To @ZZ whom. t may concern:

Be it known that I, CYRUS S. DEAN, a subject of the Queen of GreatBritain, residing at Fort Erie, in the county of lVellaiid, Province ofOntario, Canada, have invented certain new and useful Improvements inGas- Burners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others 1oskilled in the art to which it appertaiiis to make and use the saine.

My invention relates to gas-burners of that class which is designed forheating purposes.

The object of the invention is economy in i5 the consumption of thegas', perfect combustion, thorough mixing of the air with the gas, and asteady and uniform flame.

A further object of the invention is to provide simple and effectualmeans for changing zo the relative angle of the flame within certainlimits in a rapid and convenient manner to spread or contract the iiame,as the nature of the requirement may demand.

A still further object of the invention is simplicity in theconstruction of the burner consistent with efficient service andsatisfactory results.

The improvement consists of the novel features, which will behereinafter more fully 3o described and claimed, and which are shown inthe annexed drawings, in which Figure l is a central Vertical section ofa burner embodying my invention, the gas-pipe being shown in full linesand the dame-defleeting ring being shown at its highest posi tion indotted lines. Fig. 2 is a side elevation of the upper portion of theburner, showing the preferred means for effecting a vertical adjustmentof the flame-defiecting ring.

The burner proper is composed of the bowl portion I, having thedepending tubular stem il" and the inner annular shoulder il to overlapand rest upon the short pipe B, the cap G, and the gas-pipe A. The bowlportion I is 4 5 provided at its upper edge with the horizontal iiangej, between which and the outer portiong of the cap G is formed a space Ffor the escape of the gas to be burned. The cap G is imperforate andsufficiently heavy not to warp or crack, and is centrally providedsupplement the action of the annular chainbei` L to eect a thoroughmixing of the air and the gas. The dame-deflecting ring Q is adapted toencircle the outer edges of the flange j and cap G and is large enoughto leave an annular space between it and the said edges to permit thefree passage of the gas when the said ring is at its highest adjustment,as shown by the dotted lines in Fig. l. This ring is L-shaped incross-section, the horizontal portion projecting beneath the Iiangej. Tohold the ring in a relatively-fixed position to preserve a uniform spacebetween the vertical portion and the edges of the cap and the flange,projections M are provided on the bowl at proper intervals for the inneredge of the said ring to abut against. Cam portions q on the ring areprovided in sufficient number to correspond with the number and positionof the said projections M and have stops n and o at the opposite ends ofthe said cam portions to limit the turning movement of the ring Qrelative to the burner. T he pins m, extended outward from theprojections M, support the ring Q and form abutmeiits for the cams q toride upon when turning the said ring Q. To facilitate the turning of thering, a projection p is provided to be struckalight blow on either sideby a suitable instrument. The tube B has an opening d at its upper end,which is smaller than the bore of the said tube, the inner wallsflaring, as at D. The gas-pipe A is inserted within the tube aproper'distance, so that a jet of gas escaping therefrom and flaring, asindicated by the dotted lines in Fig. l, will touch the edges of theopening d. This disposition of the parts has been found to give the bestresults. The tube Bis open at its lower end and about three times aslarge as the gas-pipe A, so as to admit sufficient air.

In practice, the gas being turned on, the air will be drawn in at thebottom of the tube B and will pass through the opening d with the IOO`gas and striking the inverted cone E will be detiected outward, thencedownward by the rib Z and again rising the mixed air and gas Will enterthe annular chamber fr and escape by way of the passage F and be burned.When the flame-detlecting ring is at its lowest position, the niiameWill spread and occupy an almost horizontal position. Obviously, tochange the angle of the iame, the ring Q is 1o elevated, as hereinbeforestated, by means of the cams q and the pins m.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is-

l. A gas-burner having its cap-plate pro- "vided' on its inner face withan inverted'cone and with an annular rib concentric with the said cone,the sides of the said cone and rib curving symmetrically to form theannular 2o chamber L, and having the annular space r exterior to thesaid annular rib and Within the gas-exit, substantially as described,for the purpose specified.

2. A gas-burner having an imperforate capplate provided on its innerface with a cenas described.

4. The combination,with a gas-burner having a lateral discharge for thegas, of an annular ring surrounding the burner and mutually-coactingrpins and cams to effect avertical adj ustmet of the said ring to deflectthe ilame more or less from the horizontal, substantially as and for thepurpose described.

5. The combination, with a gas-burner having a lateral discharge for thegas and having a bowl portion and projections M and pins m, ofaflame-deflecting ring encircling the burner and guided in its verticalmovements by the said projections M and having cam portions to engagewith and ride upon the .said pins and having stops at the ends of thesaid cam portions to" engage with the said pins and limit *i themovements of the ring in each direction, substantially as set forth.

6. The combination, with a gas-burner having an inverted cone dependingfrom its capplate, ot' a tube B of uniform diameter, having its upperend contracted and provided with an opening of less diaineterthan thebore of the said tube and communicating with the gas-burner directlyopposite the apex of the said inverted cone and a gas-pipe of lessdiameter'than the bore of the said tube and inserted Within the same toa proper distance, substantially as and for the purpose specified. Intestimony whereof I affix my signaturein presence of two witnesses.
